  • Visual aid for directing light onto an optically responsive portion of an eye
    Patent number: 6299304
    Abstract: A visual aid for directing incident light rays received from an object source onto remaining optically responsive portions of an eye comprises a first light reflecting optical element resistively pivotally attached to a frame, such that the pivot axis is in a generally horizontal plane; and, a second light reflecting optical element resistively pivotally attached to the frame, such that the pivot axis is in a generally horizontal plane. The second light reflecting optical element is laterally spaced from the first light reflecting optical element such that the first and second light reflecting optical elements cooperate to direct the incident light onto the remaining optically responsive portions of the eye. In a different embodiment of the present invention, at least one corrective lens is positioned between the object source and the optically responsive portion of the eye.
